Kia has a 100,000 miles/10 Year warranty. This should be fixed under warranty.
The cause is most likely an Oxygen Sensor gone bad.
If the MIL blinks at the moment the engine bucks, them its a cold stall, were the engine is about to turn off, if the light is blinking on its own, is impossible, MIL are constantly on, because its a emission related code.
It means there's some fault code. Narrowing it down, you'd need to check to see what code it flashes at you. Key in the on position, diagnostic or cruise control switch on, hold your Set-Accel/Hold-Deccel switch and count the blinks on the check engine light... it should blink a three digit code at you... the number of times the check engine light blinks is the number, then a pause, then it blinks another number, then a pause, then it blinks another number.
get it checked, because if the ligt blinks, something is wrong.
It is important to know why a Check engine light blinks. In many cars, when it blinks so many times, it is indicating a code, which is indicating the problem number for the specific car.
I washed my car at the car wash, then I washed the engine with engine/tire cleaner with the engine running, since then my check engine light has been on. Sometimes it blinks fast, goes off and then comes back on steadily. The engine sounds like sputter, misfire, rough sound from the tailpipe. The entire engine seems to be running fine, no shaking or bouncing, just running normal. What is the problem? Thanks for your help.
you should check your engine...like now...
get a haynes manual at a library
Your traction control is probably off. There is probably a button for it. It blinks to warn you that you have the traction control option off. It may also mean there is a problem with the system.
Read the manual, but I believe it says when the cruise light blinks there is an error with the cruise control and should be checked. I have had mine blink before and then the next time I used it, it was fine.
That is the check engine light. It blinks under a severe misfire.
cycle the key three times and count the blinks of the check engine light
have vehicle scanned to determine the problem
